Network Switch Installation Guide
QuantaMesh T3000 Series
Ports of T3048-LY8
The switch chassis is equipped with the following ports:
• 48 SFP+ ports (10-Gigabit Ethernet downlink ports)
• 6 QSFP+ ports (40-Gigabit Ethernet uplink ports)
• 1 Management ports
• 1 Console port
• 1 USB port
The chassis has 48 SFP+ and 6 QSFP+ ports. Each of these ports uses an optical transceiver, active
optical cables, or direct-attached cable to connect the SFP+/QSFP+ port to the servers (downlink
connections) or hosts (uplink connections). For more information on obtaining the appropriate
SFP/QSFP+ modules, refer to
“Supported Cables and Transceivers” on page 18
.
One management port enables you to manage the switch operation using an RJ-45 Ethernet
cable.
One console port enables you to perform the initial configuration by connecting to a PC with the
RJ-45 to DB-9 serial adapter cable.
*One USB port enables you to load the configuration files from a USB storage device to the
switch’s flash memory.
NOTE:
• *The USB port function will be supported in the future release.
